Study Notes
Medical Physics
- Medical physics applies physics principles to medicine
- All areas of physics can be applied including mechanics, electromagnetism, thermodynamics, nuclear physics, optics, and fluids
- Medical physics develops new instruments and technologies for diagnosis and treatment
- The human body is complex and can be modeled using physics concepts to simulate different body activities, such as blood flow in the circulatory system
Human Body Systems
- The human body is composed of interconnected systems that work together to maintain health
- Analogies in physics can be used to simulate the function of these systems and to understand their interactions
Application to Medical Diagnosis
- Diagnostic techniques and medical instruments are based on physical principles, including measuring body temperature, blood pressure, eye pressure, and heart rate
- Medical imaging like X-rays, MRI, and ultrasound is a crucial tool for diagnosis
Medical Instruments
- Examples of medical instruments include:
- Sphygmomanometer (blood pressure)
- Digital wrist tensiometer (blood pressure)
- Medical mercury thermometer (body temperature)
- Infrared ear thermometer (body temperature)
- Otoscope (visual examination of the ear)
Magnetic Resonance Imaging (MRI)
- MRI utilizes nuclear magnetic resonance to image atomic nuclei within the body, especially hydrogen atoms in water-rich tissues
- MRI is used for diagnosing conditions like brain lesions
X-Ray Imaging
- X-rays are a common and effective medical imaging technique to visualize internal body structures
- It involves exposing a body part to ionizing radiation.
- Fluoroscopy is a type of X-ray imaging that allows doctors to observe body functions in real time, like the movement of food through the stomach.
Medical Surgery
- Laser surgery (photocoagulation) is used to treat retinal detachment by precisely targeting the affected area with a laser
- The laser creates scar tissue that fuses the detached retina back to its proper location in the eye.
Endoscopy
- Endoscopic surgery uses scopes introduced through small incisions or natural openings in the body for diagnoses and treatment
- It is a minimally invasive procedure
- An endoscope is a long, thin, flexible tube with a light and camera
Prosthesis
- Prosthesis is used to replace missing or damaged body parts
- It aims to restore the function of the lost part
- Examples of prosthetics include hearing aids and artificial limbs or joints
Artificial Devices
- Artificial devices are used to replace vital organs, like a heart or kidney, as an advanced approach to organ replacement, fulfilling a long-standing need for patients facing organ failure
